This is a great big 3 kit. To start, the wires are very flexible and more than long enough for an engine bay big 3 job. I verified that the strands are all pure copper, and the box says 100% OFC. I replaced the included nickel plate terminal lugs with tinned copper lugs of the right size for my application. The price and quality of this kit cant be beat.

Very good

This is a nice kit for the money only reason i didnt give it 5 stars is the supplied and pre installed heatshrink is to short if it was 1/4 inch longer it would cver better and stay on the wire better and it would have gotten 5 stars

Worked great for my big 3.

This is a great kit. The wire is high quality and flexible and the connectors are high quality too.

Very happy with the size of the wire, some companies have smaller 0 gauge than others (idk how that’s possible) anywho, this kit was great and I actually had to cut the wires and ended up with enough left over to run a SECOND big 3. Just need to get ring terminals for it. Overall, amazing kit for the money, definitely helped my alternator support my 1500 watt system

Las terminales muy grandes

Stopped my dimming headlights and had plenty of extra wire

Perfect for the money spent

Didn’t come with instructions
